IMPROVEMENT IN LCOlVl-l-l-ARNESSr Specilication forming part of LettersPatent No. 164,277, dated June 22, 1875; application tiled May 20, 1875.

' the several Letters Patent issued to me, dated August 4, 1868, No.80,774, and reissued and' dated August 8, 1871, in two divisions, A andB, Nos. 4,509 and 4,510, dated November 28, 1871, No. 121,258, and datedMarch 3,1875, Nos. 148,252 and 148,253.

The invention particularly relates to suoli loom-harness as are madefrom four lengths ot' yarn, as, for instance, such as shownand describedin the Letters Patent above referred to, dated March 3, 1875, Nos.148,252 and 148,253; and the present improved harness is composed ol'1yarns, from which heddle-eyes are made as in Letters Patent just abovereferred to, and all the yarns leading from and on one side ot' theheddle-eyes are secured to one and the same rig-band by knitting orsewing the 'same thereto' in any ot' the well-known modes or otherwise,and all the yarns leading from and on the other and leese side of theheddle-eyes are secured by the yarns leading from one series of eyes toone rig-band, and the yarns leading from the other series of eyes toanother and distinct rig-band, and to their respective rig-bands theyare knit or sewed in any of the wellknown modes or otherwise properlyfastened. Thus is produced a harness having three distinct rig-bands,one on one side and two on the other and leese side of its eyes, so thatif then a separate shaft be used for each rigband, and the two shafts atthe side ofthe harness, having two rig-bands, be held apart in anysuitable manner, the eyes of the harness can and will be so separated asto secure a closer and freer movement of the harnesseyes through thewarpthreads, as the harness rises and lowers, and without interferencetherewith; and, furthermore, this invention consists in the combination,with a harness of the form and construction above described, ofnovel-constructed blocks for holding the two shafts at the leese side ofthe harness, separated fromeach other, and for the suspension of theharness in a loom, all as hereinafter particularly described.

In the accompanying plate of drawings, Figure lis a plan View, showingtbe two shafts at the leese side of my improved harness, and theimproved blocks separating the same Fig. 2 is a sectional view at line xor from top to bottom of my improved harness and the shafts; and Fig. 3is a horizontal4 section along line y y, Fig. 2. Y

In the drawings, a a and b b represent the yarns or twines, from whichheddle-eyes are formed, all substantially as in Letters Patenthereiubefore referred to. rEhe yarns b at one side, A, of the harnessare secured by knitting, sewing, or otherwise to a common rigband, j',and the two yarns a at the other side, B, ot' the harness, which side isthe leese side thereof, are secured by knitting, sewing, or otherwisethe one yarn to a rig-band, g, and the other yarn to a rig-band, h. Thusthe harness is made, and into it at its rig-bands are inserted shafts C,G2, and G3, one shaft at each rig-band, in the usual manner, with har`ness having only a single rig-band at each and both of its sides, andthese two shafts, G2 and C, at the leese side of the rigband are heldapart by the insertion of blocks D between them, which blocks aresecured in such position by fastening them to the two shafts with Screwsl l, or other suitable means, that pass through the shoulders 'm of theblocks, and thence screw into the top edge of each shaft C2 Cf. (SeeFig. 2 more particularly.) The blocks 1)' are provided with eyes a, bywhich to suspend the harness in a loom.

vMy improved harness herein described possesses many features ot'advantage, and among them the following: Thatit can work the better andthe freer through the warp, because by holding apart the two shafts atone side of the harness the heddleeyes can and will be opened orseparated from each other, and thus made to occupy the position of fourdistinct rows, (see Figs. 2 and 3,) whereas with only one rig-band inplace of the two, as aforesaid, the heddleeyes would be very. close toeach other, and substantially inv only two rows;

that stronger and larger twine or yarn can be used, thus increasing thedurability of the harness and greatly economizing in the ex pense ofharness to manufacturers.

In the manufacture of the improved loomharness herein described, Iprefer to use coutinuous lengths of yarns, as particularly described inmy said Letters Patent, dated March 3, 1874:; but I do not intend tolimit myself to the same, as separate lengths of yarn may be used foreach heddle-eye formed. Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, 1s-

1. A loom-harness, having its heddle-eyes made from lengths of yarn, andthese yarns secured to three rigbands, of which rigbands one is at oneside and two at the other side of- JOSEPH SLADDIN. Witnesses:
